Problems solved by technology

In the prior art, the drive of the moving knife generally adopts a combination of gear transmission and plane crank rocker, which converts the rotation of the horizontal transmission shaft into the reciprocating swing of the rocker. This kind of driving device has a complicated structure and high cost, and The power consumption of the harvester is limited by the driving device of the harvester, so there is an urgent need for a driving device for the harvester with a simple structure, high transmission efficiency and easy maintenance

Abstract

The invention provides a driving device of a header. The driving device comprises a cylinder sleeve. A middle distance piece is fixedly arranged inside the cylinder sleeve so that an internal cavity of a cylinder body can be divided into a first cavity and a second cavity which are independent; a first piston is arranged inside the first cavity so that the first cavity can be partitioned into a first air chamber and a second air chamber which are independent and the first piston can reciprocate inside the first cavity; a second piston is arranged inside the second cavity so that the second cavity can be partitioned into a third air chamber and a fourth air chamber which are independent and the second piston can reciprocate inside the second cavity; a spindle pipe is arranged inside the cylinder sleeve and sequentially penetrates through a first end cover, the first piston, the middle distance piece, the second piston and a second end cover, and the spindle pipe can reciprocate inside the cylinder body. The driving device can directly convert linear motion of the pistons into power, and a transmission mechanism of the header is simplified, so that the efficiency of the driving device is improved.

Description

technical field [0001] The invention relates to the field of harvesters, in particular to a driving device for a harvester. Background technique [0002] Harvesting equipment is used to harvest various grains. The crops are cut by cutting knives on the harvesting table and the crops are collected for transportation, threshing and other operations. The commonly used cutting device is a scissors structure, that is, when the harvester is walking, the power is driven by the driving device through the transmission mechanism to drive the moving knife to reciprocate, so that the moving knife and the fixed knife can cut the crops. In the prior art, the drive of the moving knife generally adopts a combination of gear transmission and plane crank rocker, which converts the rotation of the horizontal transmission shaft into the reciprocating swing of the rocker. This kind of driving device has a complicated structure and high cost, and The power consumption of the harvesting platform ...
